Type description:
Take AT300QJ220-352/16 as an example
AT: brand name
300: minimum well inner diameter that can apply to (mm)
Q: submersible
J: for well use
220: flow capacity (m3/h)
352: head (m); 16: impellers
Application:
AT300QJ series submersible pump is suitable for farm irrigation, sprinkling, fountain, Rainwater Recycling System, mining drainage, emergency rescue and disaster relief, urbanwater supply, enterprises and government institutions water lifting projects. This product is low noise, high efficiency and energy saving.
Technical parameter:
Max. outer diameter:281mm; outlet diameter: DN150
Outlet connection parameter: 8 threaded studs M16×65, bolts center distance:210mm.
In order to install easily, we particularly have equipped with a matching flange (outer diameter: 242mm, inter diameter: 150mm, thickness: 20mm) consistent to the outlet.
Medium range:
1 Clean water, chilled water / cooling water, rainwater, gushing water of mining, drinking water, etc.
2 Water temperature: +5℃--+25℃
3 Solid content (mass ratio): ≤0.01%
4 PH: 6.5-8.5
5 H2S content: ≤1.5mg/L
6 Cl- content: ≤400mg/L
7 The full set must be submerged into water completely in vertical position.
Motor Parameter:
The submersible motor is lubricated by clean water. It must be filled with clean water, or else its service life will be lessen. If you forget filling, the motor will be broken.
Motor protection level: IPX8
Power source:
Rated voltage: 380v. Frequency: 50Hz or voltage: 660v, frequency: 50Hz
If you need special voltage or frequency,please inform us in advance.
Materials:
Impeller: Cast iron HT200, or tin bronze,such as ZCuSn3Zn8Pb6Ni1
Pump bowl: Cast iron HT200, or stainless steel, such as 2Gr13 .304
Pump shaft: Cold-drawn steel with chrome plating, or stainless steel 2Gr13 (1050℃ thermal refining, enhancen torsional moment)
Motor Seal: Rubber O-ring seal, mechanical seal
Motor regulating sleeve: rubber
Advantages:
1 Easy installation
2 Low noise, multistage
3 Built-in checkvalve avoiding water hammer impact.
4 High head with singlestage, strong stability,the shaft diameter φ42mm, improving the equipment’s torsional property. Bearing liner is made of natural rubber and more wear-resisting, meanwhile we have attached with imported hard bearing liner.
Supplys:
AT300QJ series submersible pump (including the body and motor), built-in checkvalve, 1 flange matching with outlet, 8 threaded studs 16×65, 1 maintanence instruction, 1 conformity certificate, 1 packing list, external packing.
Friendly reminder:
For the customers’ convenience and our products’ quality, all the related products are manufactured by ourselves. The products detailed information are as follows:
a. All kinds of lifting pipes including high-frequency welded pipes (dia.25mm-500mm); Connection type: flange connection, screw connection and clamp connection.They are made accurately by machine tools.
b. Pipe clamp: the length is 50mm-500mm (we can produce the other different spans according to your requirements).
c. Wellhead devices: return flow wellhead instruments (applied to ground source heat pump), general pump seat (we have innovated and designed this kind of pump seat by replacing the original iron castings with steel plate welding; the cable lead-in hole has also been improved by substituting the U hole for middle lead-in hole, thus making more convenient for the customers.)
d. Desander: avoiding blocking and polluting by sand in water. And it contributes to long service life.
e. Related products:submersible cable, starting cabinet, frequency conversion cabinet, transformer, electric generating set, etc.
f. According to the the conditions on the spot, we also supply the design proposals about pipe network, tank and installation.
